* Nuke all occurrences of usbd_abort_pipe() if it gets called rightmglocker2020-07-311-4/+1
| | | | | | | | | | before usbd_close_pipe(), since usbd_close_pipe() already takes care about aborting non-empty pipes. As investigated by gerhard@ usbdi.c rev. 1.57 did add usbd_abort_pipe() to usbd_close_pipe(), but the drivers didn't get cleaned up afterwards. ok gerhard@

* move counting if_opackets next to counting if_obytes in if_enqueue.dlg2017-01-221-2/+1
| | | | | | | this means packets are consistently counted in one place, unlike the many and various ways that drivers thought they should do it. ok mpi@ deraadt@
* Avoid calling usbd_set_config_no() in *_attach() and let the stack dompi2016-11-061-9/+2
| | | | | | | | | it instead. If anything bad happen due to a malformed descriptor it makes no sense to try to attach a driver, and bail before probing. This is similar to the change to avoid calling usbd_set_config_index().

* replace IFF_OACTIVE manipulation with mpsafe operations.dlg2015-11-251-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | there are two things shared between the network stack and drivers in the send path: the send queue and the IFF_OACTIVE flag. the send queue is now protected by a mutex. this diff makes the oactive functionality mpsafe too. IFF_OACTIVE is part of if_flags. there are two problems with that. firstly, if_flags is a short and we dont have any MI atomic operations to manipulate a short. secondly, while we could make the IFF_OACTIVE operates mpsafe, all changes to other flags would have to be made safe at the same time, otherwise a read-modify-write cycle on their updates could clobber the oactive change. instead, this moves the oactive mark into struct ifqueue and provides an API for changing it. there's ifq_set_oactive, ifq_clr_oactive, and ifq_is_oactive. these are modelled on ifsq_set_oactive, ifsq_clr_oactive, and ifsq_is_oactive in dragonflybsd. this diff includes changes to all the drivers manipulating IFF_OACTIVE to now use the ifsq_{set,clr_is}_oactive API too. ok kettenis@ mpi@ jmatthew@ deraadt@

* shuffle struct ifqueue so in flight mbufs are protected by a mutex.dlg2015-11-201-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the code is refactored so the IFQ macros call newly implemented ifq functions. the ifq code is split so each discipline (priq and hfsc in our case) is an opaque set of operations that the common ifq code can call. the common code does the locking, accounting (ifq_len manipulation), and freeing of the mbuf if the disciplines enqueue function rejects it. theyre kind of like bufqs in the block layer with their fifo and nscan disciplines. the new api also supports atomic switching of disciplines at runtime. the hfsc setup in pf_ioctl.c has been tweaked to build a complete hfsc_if structure which it attaches to the send queue in a single operation, rather than attaching to the interface up front and building up a list of queues. the send queue is now mutexed, which raises the expectation that packets can be enqueued or purged on one cpu while another cpu is dequeueing them in a driver for transmission. a lot of drivers use IFQ_POLL to peek at an mbuf and attempt to fit it on the ring before committing to it with a later IFQ_DEQUEUE operation. if the mbuf gets freed in between the POLL and DEQUEUE operations, fireworks will ensue. to avoid this, the ifq api introduces ifq_deq_begin, ifq_deq_rollback, and ifq_deq_commit. ifq_deq_begin allows a driver to take the ifq mutex and get a reference to the mbuf they wish to try and tx. if there's space, they can ifq_deq_commit it to remove the mbuf and release the mutex. if there's no space, ifq_deq_rollback simply releases the mutex. this api was developed to make updating the drivers using IFQ_POLL easy, instead of having to do significant semantic changes to avoid POLL that we cannot test on all the hardware. the common code has been tested pretty hard, and all the driver modifications are straightforward except for de(4). if that breaks it can be dealt with later. ok mpi@ jmatthew@

| | | | | | | | | | | | | | set the 'dying' flag of a device. Such handlers are useless now that usbd_detach() already set this flag. Even if the purpose of this flag is questionnable on OpenBSD because DVACT_DEACTIVATE acts as a pre-detach event, this is just a first small step towards the simplification of the autoconf(9) device states. This cleaning is now possible thanks to the work of pirofti@ to convert all the USB drivers to properly use usbd_is_dying(). Discussed many times with deraadt@

| | | | | | | | | | | be run from the generic task kthread, because xfers that need to be aborted block newly queued tasks from running (i.e. the xfer to be aborted blocks the abort of that task). as there are now three types of usb tasks, add an argument to usb_init_task() and another member to struct usb_task to specify the task type. fixes boot hangs that are showing up because we now use usb tasks to attach/detach usb devices.
